Hoping to change that, a team of scientists stationed in Antarctica has run a successful test of the South Pole Telescope, a 10-meter-wide behemoth that just might solve the mystery of dark energy. Nine institutions came together to develop the telescope, with the $19.2-million bill picked up primarily by the National Science Foundation. Assembly required pilots from the New York Air National Guard, aircraft from Operation Deep Freeze (the U.S. military's ongoing mission in Antarctica), and round-the-clock construction since November in the unrelenting cold of one of Earth's most hostile climates. Finally, on February 16, the group collected what's known as first light. They aimed the telescope skyward and saw . . . light—and dark, and Jupiter.
